DESCRIPTION

36       This plugin support multiple types of hashed or unhashed DNS
37       blocklists.
38
39       OPTS refers to multiple generic options:
40
41         raw      do not hash data, query as is
42         md5      hash query with MD5
43         sha1     hash query with SHA1
44         case     keep case before hashing, default is to lowercase
45         max=x    maximum number of queries
46         shuffle  if max exceeded, random shuffle queries before truncating to limit
47
48       Multiple options can be separated with slash or other non-word
49       character.  If OPTS is empty ('') or missing, default is used.
50
51       HEADERS refers to slash separated list of Headers to process:
52
53         ALL           all headers
54         ALLFROM       all From headers as returned by $pms->all_from_addrs()
55         EnvelopeFrom  message envelope from (Return-Path etc)
56         HeaderName    any header as used with $pms->get()
57
58       if HEADERS is empty ('') or missing, default is used.
59
60       header RULE check_hashbl_emails('bl.example.invalid/A', 'OPTS',
61       'HEADERS/body', '^127\.')
62           Check email addresses from DNS list, "body" can be specified along
63           with headers to search body for emails.  Optional subtest regexp to
64           match DNS answer.  Note that eval rule type must always be
65           "header".
66
67           DNS query type can be appended to list with /A (default) or /TXT.
68
69           Additional supported OPTS:
70
71             nodot    strip username dots from email
72             notag    strip username tags from email
73             nouri    ignore emails inside uris
74             noquote  ignore emails inside < > or possible quotings
75
76           Default OPTS: sha1/notag/noquote/max=10/shuffle
77
78           Default HEADERS: ALLFROM/Reply-To/body
79
80           For existing public email blacklist, see: http://msbl.org/ebl.html
81
82             # Working example, see http://msbl.org/ebl.html before usage
83             header   HASHBL_EMAIL eval:check_hashbl_emails('ebl.msbl.org')
84             describe HASHBL_EMAIL Message contains email address found on EBL
85             priority HASHBL_EMAIL -100 # required priority to launch async lookups early
86             tflags   HASHBL_EMAIL net
87
88           header RULE check_hashbl_uris('bl.example.invalid/A', 'OPTS',
89           '^127\.')
90               Check uris from DNS list, optional subtest regexp to match DNS
91               answer.
92
93               DNS query type can be appended to list with /A (default) or
94               /TXT.
95
96               Default OPTS: sha1/max=10/shuffle
97
98       body RULE check_hashbl_bodyre('bl.example.invalid/A', 'OPTS',
99       '\b(match)\b', '^127\.')
100           Search body for matching regexp and query the string captured.
101           Regexp must have a single capture ( ) for the string ($1).
102           Optional subtest regexp to match DNS answer.  Note that eval rule
103           type must be "body" or "rawbody".
